Well another scratch built model from history. Korean Admiral Yi Sun-sin used this type of ship when fighting the Japanese about 1592.
At the moment am sorting out the size and have decided to do it in 1/144 scale this will give a model of about 250mm long by 69mm wide. Have just fastened a couple of bits of wood together to make the former for the top cabin, this will be covered with thin strips of wood and plastic, then its onto the lower hull,masts and dragons head.
Have had this model in my head for a while and got the Osprey book to provide more info alongside the images on the internet I have found.
